AI Technical Summary
Mining cables are easily ignited, corroded, or broken in harsh environments, leading to power line outages. Furthermore, conventional drag cables have short service life, insufficient effective length, large outer diameter, and poor torsional resistance.
The cable features a braided reinforcement layer with 36 aramid ropes and 24 spindles in a special structure. There are also 12 spindles with two aramid ropes per spindle, 12 spindles with one aramid rope per spindle, and two adjacent strands per spindle, all circulated on the coil. Combined with tinned copper wire shielding and a low-smoke halogen-free rubber sheath, this enhances the cable's torsional resistance and insulation.
It improves the cable's torsional resistance and abrasion resistance, extends the cable's service life, reduces construction difficulty, and enhances the cable's stability and insulation.
